Administrative data

Endpoint:
distribution modelling
Type of information:
(Q)SAR
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
The results for key lower molecular weight components of Cashew Nutshell Extract, Decarboxylated, Distillation Residue (Distilled Residue Grade) are classified as Klimisch Code 2 (reliable with restrictions) as they are generated from a recognised model (US EPA EpiWin version 3.12). This data is not required under REACH, but is included as additional information. As the model used to generate this prediction has been superseeded by EpiWin v4.00, a QPRF is not included.
Justification for type of information:
QSAR prediction: migrated from IUCLID 5.6

Applicant's summary and conclusion

Conclusions:
Based on the estimations as a whole, the major lower molecular weight components of Cashew Nutshell Extract, Decarboxylated, Distillation Residue (Distilled Residue Grade), namely cardanol and cardol liquid will distribute mainly to soils (37.3-77.7%) if released to the air compartment, almost exclusively to sediment (94.8-97.3%) of released to water, exclusively to soil if released to soil and mainly to sediment (66.9-69.9%) if released simultaneously to all air, soil and water compartments.
